Gov. Peter Shumlin is working with the state Health Department to draft a more effective emergency ban on ingredients used to make the hallucinogenic drug known as bath salts.

Sarah Vose of the Health Department said the rule will add over 30 bath salt-type compounds. She said the hope is to stay ahead of manufacturers who are tweaking chemicals to make them fall outside of what's listed.

State health boards will review the additional ingredient to add to the regulated drug list. Health and Human Services Secretary Doug Racine is expected to approve it Friday. Shumlin is expected to give his approval on July 25.
